Clay is the enrichment and research layer of most modern outbound stacks. It pulls from dozens of data providers, runs AI research agents on every row, and pushes the result into your CRM or sequencer. Building a table is easy. Building one that stays accurate, stays inside a credit budget, and feeds reps something they actually send is the hard part, and that is why Clay agencies exist.

This guide compares 9 Clay agencies and Clay experts on what they build, their tier in Clay's own partner directory, their published pricing floors, and who each one fits. Every tier and price below was checked on clay.com/experts or the agency's own site on October 21, 2026.

Disclosure: ManasFlow wrote this guide and ranks itself first. The reason is scope: we set up Clay and build the automation around it (sequencer, CRM sync, routing, monitoring) in one team. ManasFlow is not listed in Clay's partner directory. If you specifically want a Clay-tiered partner, or a team that only does Clay, one of the agencies ranked 2 to 8 will fit better, and we say which below.

Best Clay agencies: a brief overview

ManasFlow: Best overall Clay agency for automation-first teams: Clay enrichment plus the Instantly, HeyReach, CRM and n8n automation around it, built and run by one team.
The Kiln: Best for a Clay-native data system, built by a team of former Clay employees.
Growth Engine X: Best for high-volume cold email that runs on Clay, done for you.
RevPartners: Best for HubSpot companies that want Clay wired into the CRM, at a published fixed price.
Go Nimbly: Best for enterprise Clay rollouts with governance, training, and change management.
FullFunnel: Best for mid-market teams that want an Elite Studio partner with a one-month minimum.
SalesCaptain: Best for SMB done-for-you outbound across email and LinkedIn.
fuelgtm.io: Best budget pick: one hands-on Clay and Salesforce or HubSpot engineer.
Sculpted: Best for a fixed-scope, four-week CRM cleanup and enrichment sprint.

Clay's partner directory groups firms into four tiers: Elite Studio, Studio, Advanced Artisan and Artisan. Clay does not publish the criteria behind each tier, so treat the tier as one signal, not a quality score. The directory listed 189 partners when we checked.

1. ManasFlow, best overall Clay agency for automation-first teams

ManasFlow is an AI automation agency that treats Clay as one layer of an outbound system rather than the whole job. We build the Clay tables (ICP filters, waterfall enrichment, AI research columns, scoring), then wire everything downstream: verified contacts into Instantly or HeyReach sequences, replies and meetings back into your CRM, and n8n jobs that keep the data clean. Our own outbound runs on Instantly, HeyReach, Attio, Unipile and n8n, so the system we hand over is the kind we operate every day.

The Clay agency service is built for teams whose bottleneck is everything around the table: who owns the sending domains, what happens when a lead replies, and how enrichment stays inside a credit budget. A typical build is a signal-based outbound workflow: a buying signal triggers Clay enrichment and verification, the signal becomes the first line of the email, and the reply is logged in the CRM.

Main features

Clay table design: ICP filters, waterfall enrichment, AI research columns, lead scoring
Downstream wiring into Instantly, HeyReach, HubSpot, Salesforce or Attio
n8n automations for routing, deduplication and Slack alerts
Human approval before messages send, per-day caps and suppression lists, as described in our GTM automation workflow
Option to place an embedded GTM engineer on your team instead of a project

Best for

Teams that want one owner for Clay, the sequencer and the CRM sync
Companies that tried Clay in-house and stalled on the parts after the table
Revenue operations leads who want documented systems they can run after handover

Pricing

Scoped Clay and outbound builds: custom quote after a discovery call
Embedded GTM engineer placement from $60,000/year, with a 90-day replacement guarantee

Pros

Clay, sending infrastructure and CRM handled by one team, so nothing breaks at the handoff between vendors
Automation depth beyond Clay (n8n, AI agents, CRM hygiene jobs)
Choice between a scoped project and an embedded engineer

Cons

Not listed in Clay's partner directory. Buyers who require a Clay-tiered partner should shortlist The Kiln, Go Nimbly or another Elite Studio firm
Not the cheapest route if you only need a single enrichment table built

2. The Kiln, best for a Clay-native data system

The Kiln is a Clay agency staffed by former Clay employees. They build Clay implementations from the ground up: waterfall enrichment tables, total addressable market (TAM) mapping, AI-written outbound sourced from Clay tables, and inbound lead enrichment and scoring. They also normalize and enrich CRM records.

The Kiln holds Elite Studio status in Clay's directory and keeps its client list small on purpose. Its homepage announces that it has been acquired by 2X, so ask how the acquisition changes team and pricing before you sign. If your priority is the cleanest possible Clay architecture from people who know the product from the inside, this is the strongest specialist pick.

Main features

Clay implementation and table architecture
TAM mapping and waterfall enrichment
AI-written outbound from Clay data
Inbound enrichment and lead scoring

Best for

Funded teams that want Clay set up correctly by Clay specialists
RevOps teams planning to run Clay in-house after the build

Pricing

$10k+ per month, 3-month minimum (Clay directory profile)

Pros

Deep product knowledge from a former Clay team
Elite Studio tier in Clay's directory

Cons

The $10k+ monthly floor rules out most small teams
Limited client capacity, so expect a waitlist or a selective intake
Recently acquired by 2X, so confirm current terms directly

3. Growth Engine X, best for high-volume outbound on Clay

Growth Engine X, founded by Eric Nowoslawski, is a done-for-you cold email agency that runs its list building and validation on Clay. Clients get the campaigns and keep the Clay tables behind them. The agency states it sends more than 8 million emails a month and generated 62,000+ positive responses in 2025.

Its Clay profile says it works with B2B companies whose customer lifetime value is above $5,000. Note that growthenginex.com redirects to coldoutbound.com.

Main features

Done-for-you cold email at high volume
Clay list building with Claygent validation
Client keeps the Clay tables
Free test campaign for qualifying businesses

Best for

B2B companies with LTV above $5,000 that want outbound fully run for them
Teams testing whether cold email works for their market before hiring

Pricing

Custom quote; 3-month minimum (Clay directory profile)

Pros

Elite Studio tier and a public, measurable sending scale
Free test campaign lowers the risk of the first engagement

Cons

Focused on cold email, not CRM architecture or RevOps
The LTV threshold excludes lower-ticket businesses

4. RevPartners, best for HubSpot plus Clay

RevPartners is a RevOps firm that sells Clay implementation as a HubSpot-connected GTM engine. The work covers CRM enrichment and standardization, signal-triggered outbound, and scoring models and prospecting dashboards inside HubSpot. The firm states it holds Elite status with both Clay and HubSpot.

It is also one of the few Clay agencies with a published price: a $25,000 one-time Clay implementation with a 90-day launch, including the HubSpot integration and five playbooks. If you are a HubSpot shop, read our guide to the best HubSpot agencies too.

Main features

HubSpot and Clay integration
CRM enrichment and field standardization
Signal-triggered outbound
Scoring models and prospecting dashboards in HubSpot

Best for

HubSpot companies that want enriched, scored records inside the CRM
Buyers who need a fixed price before procurement signs off

Pricing

Clay implementation: $25,000 one-time, 90-day launch
RevOps-as-a-Service: $9,850 to $27,000 per month plus a $5,000 onboarding fee (revpartners.io/pricing)

Pros

Transparent published pricing
Elite Studio tier in Clay's directory

Cons

Built around HubSpot, so Salesforce teams get less out of it
$25,000 up front is a large first commitment

5. Go Nimbly, best for enterprise Clay rollouts

Go Nimbly runs enterprise Clay programs: architecture and integration, governance, credit-cost optimization, and phased rollouts with change management. Use cases include CRM hygiene, territory planning and intent orchestration. Engagements end with documentation, training and 30 days of hypercare.

Its engagement tiers run from about three months (Foundations) to six months and longer (Enterprise). That pace suits companies where Clay touches several departments and needs rules about who can spend credits and change tables.

Main features

Enterprise Clay architecture and integrations
Governance and credit-cost optimization
Phased rollouts with change management
Training and 30-day hypercare

Best for

Enterprise RevOps teams rolling Clay out across regions or business units
Companies that need training built into delivery

Pricing

$10k+ per month, 3-month minimum (Clay directory profile)

Pros

Governance and enablement are part of the scope, not extras
Elite Studio tier in Clay's directory

Cons

Enterprise pace and price
Not a done-for-you outbound shop

6. FullFunnel, best for an Elite partner on a short commitment

FullFunnel builds what it calls a Clay Data Engine (Enterprise or Pro tiers), administers Clay for clients, runs managed GTM teams, and ships pre-built agents for stalled-lead reactivation, referral intelligence and CRM enrichment. The firm states it has served 1,000+ B2B organizations since 2013.

Its Clay profile lists a $5k+ monthly floor and a one-month minimum, the lowest commitment among the Elite Studio firms we checked.

Main features

Clay Data Engine build
Ongoing Clay administration
Managed GTM teams
Pre-built reactivation and enrichment agents

Best for

Mid-market teams that want an Elite Studio partner without a quarter-long lock-in

Pricing

$5k+ per month, 1-month minimum (Clay directory profile)

Pros

Shortest minimum among Elite Studio firms checked
Broad GTM services if you need more than Clay

Cons

Clay is one service line in a broad agency, so ask who on the team works on your tables

7. SalesCaptain, best for SMB email and LinkedIn outbound

SalesCaptain runs Clay-powered outbound across cold email and LinkedIn: list building, personalization, CRM enrichment into HubSpot or Salesforce, and Clay and AI tool enablement for sales teams. Its Clay profile lists a one-month minimum and "any budget."

Its website calls the firm a Clay Enterprise Partner. Clay's own directory lists it as Advanced Artisan, so rely on the directory when comparing tiers.

Main features

Done-for-you email and LinkedIn outbound
Clay list building and personalization
CRM enrichment into HubSpot or Salesforce

Best for

SMB and mid-market teams that want multichannel outbound with a short commitment

Pricing

Custom quote; 1-month minimum (Clay directory profile)

Outbound-led, with less depth in enterprise data architecture
